Its a nice plane to fly, specially if it comes equiped with HUD. Flying bizjets the FMS may appear familiar to you, as it is a generic not compare to Airbus or Boeing. The vertical profile is very handy, just keep in mind it doesnt takes decelaration into account, specially approaching with tailwind try to stay a little below the green until configured on final. Side windows dont have heating or defog, flying in the moist tropics you may even open the window for taxi. Pressurization is a weak point in the construction, try to get an earlier decent or you will pop your ears and your Paxs as the Outflowvalve works harsh. Always keep an eye on the Bleeds, if pressure starts to vary a lot a failure might be imminent, not uncommon on the type, keep procedure for decompressure and emergency decent always in mind, specially if you should get dispached with 1 Pack Off, choose a lower Level, add fuel for a contingency, it do happen! Flaps are electric and therefore quite slow, and sensitive, using them to add drag in order to reduce speed is not a good idea. Low rate is slow rate, if you antecipate it configure early.
Should you fly both 190 and 195, handling is not so different as it is FbW, but I got used to flare earlier on the 195 compared to 190, 195 likes to hard land and 190 to float. If you have speed increments for gust, crosswinds, etc fly the plane to the ground and reduce thrust earlier, else it will float. Seats are not the most confortables for longer flights...
Wx radar often oversees something, specially when it is embedded, we used to call him Steve (after Steve Wonder). It is amazing how short you can stop the bird, even fullhouse, carbon brakes do a great job, together with the deceleration scale on the HUD you will be tempted to disconsider use of autobrake.
All in all ops are easy, only the load of electronic put into it make the EICAS bring up bogus messages quite frequently.
Have fun!
